Up To 5000GPM Diesel Engine Driven Vertial Turbine Fire Pump With NFPA20 Standard
Vertical Turbine Pump Introduction:
These pumps are helpful in areas where water is scarce, but also when installing an above-ground water storage tank is not desirable. An added advantage to a vertical turbine pump is that almost any length and discharge pressure of the pump can be ordered. Several impellers can be added for additional pressure. When properly installed, there is no longer a concern about air in the suction pipe, or any of the priming concerns. With each additional impeller added, you are adding to the pump “churn” or shut-off point on its curve, so additional unwanted pressure is often seen at lower operational flows.
How it Works:
The vertical turbine pump is normally driven by an AC electric induction motor or a diesel engine via a right angle drive. The end of the pump consists of a rotating impeller that is joined to a shaft and guides the well water into a diffuser casing known as a bowl.
Pumps with multi-stage arrangements use several impellers on a single shaft to generate higher pressure that would be required for pumping water from deeper wells or where higher pressure (head) is required at ground level.
A vertical turbine pump works when water comes through the pump from the bottom through a bell-shaped device known as a suction bell. The water then moves into the first stage impeller, which increases the velocity of the water. The water then moves into the diffuser casing directly above the impeller, where the high velocity energy is transformed into high pressure. The diffuser casing also guides the fluid into the next impeller located directly above the diffuser casing. The process goes on through all the stages in the pump.
